The groups urged a federal court to prevent the Recording Industry Association of America (RIAA) from forcing Internet Service Provider Charter Communications to identify customers the RIAA has accused of offering infringing music on a peer-to-peer system. In December 2003, a federal appeals court in Washington, DC, ruled that the RIAA could not use special, non-judicial subpoenas under the Digital Millennium Copyright Act (DMCA) demanding that Verizon identify unnamed alleged filesharers.

"The RIAA wants to use the Charter case to erase the D.C. court's Verizon decision and set back Internet users' privacy," said EFF Legal Director Cindy Cohn. "The courts should require careful judicial consideration of facts supporting any accusations and hear the other side of the story before violating the privacy of any Internet user."

EFF, along with 21 other groups, including the American Civil Liberties Union, Consumer Federation of America, and the Computer & Communications Industry Association, filed a "friend of the court" brief urging that the same strong protections that apply for anonymous speech in other contexts also apply for claims of copyright infringement.

"Our privacy and free speech rights should not be collateral damage in the RIAA's war against the digital music revolution," added Cohn.
